, SPINNING -NIACHINE- SPECIFICATION forming part of Letters Patent No. 752,829, dated February 23, 1904.

Application filed May 10, 1902. Serial No. 106,810. (No model.)

To all whom it may concern:

Be it known that I, Lnon DUGAUQUIER, a

subject of the King of Belgium, residing at Houdeng-Goegnies, Belgium, have invented certain new and useful Improvements in Spinning-Machines, of which the following is a specification.

Many spinning-machines of various kinds exist, but they are all defective, as the winding is effected by friction or otherwise. Indeed, it is not with organs so capricious as those which act by friction that regular and rapid operation can be hoped for. Hence of the winding or irregularities of twist or output. It is the same in cases where the winding is performed without friction, for

hitherto it has been impossible to regulate the winding so as to make it correspond mathematically with the production and the twist. This defect results from the fact that methods of effecting this regulation have always been based on a false principle-namely, that the speed of rotation of the bobbin should be modified after every layer of winding by an amount regular or progressively regularl Now in order that the winding on the bobbin may be regular the bobbin should wind for every turn of the flier (the speed of which is uniform) a constant length of thread. Therefore for each revolution of the flier the bobbin must make besides the fliers motion a fraction of a revolution which bears to a complete revolution the ratio which the length to be wound per revolution of the flier bear s tg 1 pposing the length a' complete winding. to be wound per revolution of the flier to be we have the following ratio:

7r 1r 1 one convolution J D thread may be supposed to be a fraction of The ob ect of my invention is to regulate mathematically at will, first, the amount of winding per twist of thread, and, secondly, the number of twists per minute. If I obtain in each minute a regular and determinable number of twists, and if I can by the winding give a regular and determined length for each twist, the spinning and winding can go on regularly per minute and per'yard. The outfit will therefore be regular and as great as may be desired, and it will be the same with thetwist and winding, which will be effected without friction and with tension as low as may be desired.

For the sake of simplifying illustration I have shown in the drawings this present improvement applied to a spinning-machine. I could also apply it to a spindle-machine. For this it would be suifi cient either to suppress the drawing-rollers or to work these rollers by organs having a speed of rotation corresponding. with that of the flier.

In the accompanying drawings, Figures 1 and 2 are front views of the spinning-machine. Fig. 3 1s a side View. F1g.4 1s aview,

partly sectional, of the diflerential gear separate; and Fig. 5 is across-sectional view along the line A B of Fig. L.

The machine is mounted on a suitable frame consisting of four supports 1, provided with bearings and connected by ties. The movement'of the motor is transmitted to a shaft 2 by two pairs of pulleys of different diameters, 3 3, each pair comprising a fast and a loose pulley,

so that the shaft 2 can be driven'attwo very different speeds and that the machine can be started and stopped at will. On the shaft 2 is keyed a conical drum 4, which by a belt drives a second conical drum 6 like thefirst,

but arranged in the opposite direction and ries the flier 8, the second also by a straight belt connecting the conical drum 12 to a second inversely-arranged conical drum 13 of respectively smaller diameters and positively driving the. bobbin 11. The shaft 15, which carries the drum 13, is hollow, so as to inclose the shaft 14, which has at its end a spring-bolt 16, arranged to enter a notch on the shaft when the shaft 14: is pushed home-that is to say, when its other end enters the sleeve of the flier, where it can turn subject to light friction. The two shafts 14 and 15 are then positively connected. Besides, on the part of the shaft 1 1 which receives the bobbin 11 is formed a longitudinal groove, in which slides a key fixed to the bobbin, which can thus slide along the shaft l hturning with it and the shaft 15. Thus the flier makes always the same number of revolutions per minute as the main shaft 5, and the bobbin makes a smaller number. of revolutions.

Differential gear 17, a plan of which on enlarged scale is shown in Fig. 1, is fixed on the frame. It consists, substantially, of a box 17, which can turn on its two hollow axes and contains, first, two equal toothed wheels 18 a'nd'2l, keyed on the ends of two shafts 2 1 and 25, which are in line and have, respectively, at their other ends outside the box, a pulley 23 and a toothed change-wheel 26; second, two special pinions 19 and 20, having the same number of teeth as the pinions 18 and 21, and abalance-roller. The pinions 19 and 20 gear, respectively, with the Wheels 18 and 21 and gear together by their inner part. The axes of thesetwo pinions 19 and 20 are journaled in the side walls of the box 17. The pulley is connected by a cross-belt to a pulley 31 of half its diameter, that is keyed on the shaft 15 of the bobbin. The pulley 23 is connected by a like belt to a pulley 22 of the same diameter, keyed on the shaft 5.

Let us examine the action of the actuatingorgans of the differential gear, assuming that the flier and the bobbin turn to theleft and bearingin mind that the pinions 18, 19, 20, and 21 are formed with the same number of teeth. I

A. 'If we assume the pulley 23 turning alone to the left, the pulley 3O remaining'stationary, we have then the case of a pinion 18 actu'ating another pinion 21 through the medium of two pinions 19 and 20. These four pinions being formed with the same number of teeth, it results thatthe pinion 21 turns at the same speed as the pinion 18, but in the opposite di r'ection-namely, to the right.

B. If we suppose the pulley 23 stationary, the pulley 30 turning alone to the left, what will be the operation of the differential gear? If the pinion 20 be fixedto the box 17, the same teeth of both pinions 20 and 21 should remain engaged, and the pinion 21 should make one turn to the left with the pinion 20 and with the box 17 for each revolution'of the pulley 30 to the left; but instead of being fixed the pinion 20 turns in the opposite direction as the box 17 and causes the speed of the pinion 21 to be accordingly increased. Infact, the immobility of the pinion 18 causes the pinion 19 to turn at the same speed and direction as the box 17. This pinion 19 actuates the pinion 20, and consequently the pinion 21, this latter making one turn for each revolution of the pinion 19 or of the pulley 30 at the same speed and .direction as the box 17 namely, to the left.

To sum up, the wheel 21 turns in the direction of the box 17, making one revolution, due to its engagement with the pinion 20, and a supplemental revolution, due to that of the pinion 19. These points being established, if we represent by n the number of turns made by'the bobbin within the time there is awinding made on the bobbin the number of turns of the flier made within the same time must obviously be (n 1). The number of turns made by the pulleys 30 and 23 during the same time are consequently and (n 1,) respectively,

on account of the ratio of the diameters of the pulleys 31 30 and 22 23. These quantities belng given, if we suppose the pulley 30 to make gturns to the left, the pinion 21 will make 2 turns to the left. During the same 2 (n llequals one turn to the left. a

being any number whatever, it results that whatever may be the relative speeds of the flier and of the bobbin the pinion 21 will make one turn every time there is a winding made on the bobbin. The shaft 25 has a gear 26, which drives the gear 27, and consequently the shaft 28, a part 29 of which is screwed with crossing-threads, so as to cause the sleeve 32, which surrounds it, to move to and fro, which movement is conveyed to the rod 37 by the lever 35, pivoted at 39 and to the bobbin 11 by the fork 4:0. The lever has at its upper end a slot 36, receiving a pin 38 on the rod 37, which imparts its motion to the bobbin 11 by means of the fork 4:0, which embraces a grooved pulley fixed on the bobbin. Thelength of the threaded part 29 is such as to give the upper end of the lever 35 a motion equivalent to the available length of the bobbin. A pin 33, fixed on the sleeve 32, enters a hole 345 of the lever '35. This pin can be varied in height on the sleeve, so as to modify the stroke of the lever 35 to suit the thickness of the thread. The shaft 28 has also at its end a small pinion 45, which gears with a free wheel 16. The ratio of 16 to is the number of the threads ijo of 29, so that the wheel 46 makes one revolution every time the sleeve 32, and consequently the bobbinll, makes a complete travbobbin.

On thevwheel46 is a pin 47, which, as it passes, lifts the head of the lever 49 by hearing on its tail and the position of which is adjusted, so that it escapes the lever 49 at the moment when the .bobbin completes its traverse. The lever 49, with the aid of its counterweight 52 and a pawl 51, actuates a toothed wheel 50, fixedon its axis 48, through a fraction of a revolution determined by the extent of its fall. This fall is adjusted and limited by a cam 59, against which strikes the pin 53, fixed on the lever 49. This cam should differ for every kind of thread. It is turned by the fall of the lever 49 by means of asprocket-wheel 66, fixed on the shaft 48, which the lever turns as it falls and which actuates by a chain 60, the free ends of which are strained and balanced by the weights 61 62, a second sprocket-wheel 67, keyed on the;

axis of the cam 59. If the cam 59 has in the first instance been carefully set, so that the first fall of the lever 49 is the longest possible, then ateach fresh fall of the lever the cam presents a greater and greater radius, which progressively lessens the extent of fall, and on the extent of the fall depends the advance of the nut-fork 42 on the curved part 41 of the shaft 48, and consequently the shift of the band guided by the fork 42 and the retardation of the bobbin 11. The cam 59 therefore exactly regulates the retardation of the bobbin after each layer of thread wound on it. The two weights6l 62 serve to give a certain tension to the chain and also to allow the return of the cam 59 and the nut-fork 42 totheir initial position when the operation is completed. It is sufficient to raise the weight 61 after having first reversed the pawl 51. Actuated by the other weight 62, the chain moves back over the course which it had passed and brings back the cam 59 and the belt of the drums 12 and 13 to their primary position. In order to, regulate this return, care is taken on beginning to spin to bring back a stop-ring against the nut-fork 42 and The. machine operates as follows: Pressing the spring 16 the shaft 14 is drawn outward untilit does not extend. beyond the hollow shaft 15. A bobbin 11 is placed in the fork 40, and the shaft 14 is pushed through the A thread end is then led through the hollow shaft 56 and over the rollers 57 and fixed to the bobbin. The stop-ring 43 for the fork-nut is fixed, and the belt is brought back by the fork as far as the stop permits.

The machine is started by pressing the lever 63, which by means of the rod 64 and is equal to the length of thread wound per turn of the flier, and this length depends on the diameter of the convolution and on the place occupied by the belt on the drums 12 and13. For the first layer on the bobbin the A length of twist is therefore settled by the place occupied by the belt on the said drums 12 and 13. Now the number of twists being the number of revolutions of the flier, and consequently depending on the position of the belt on the drums 4 and 6, on the other hand, the length of twist being given by the place occupied by the belt on the drums 12 and 13, the result will be that for the first layer of thread on the bobbin the number of twists per minute and per yard is fixed. To obtain regular spinning, it is only necessary to maintain for succeeding layers the same extent of thread wound per turn of flier. 1f the bobbin did not vary in diameter, the belt might be kept on the drums l2 and 13 in the position suited to the desired length of twist; but for every layer of thread received by the bobbin it increases in diameter by twice the thickness of the thread. Therefore to maintain regularity of twist immediately on each layer being completed and only then must the speed of the bobbin he suddenly reduced by a suitable amount, still maintaining regularity of layer. Thisreduction of speed is obtained at the end of each traverse of the bobbin by means of the shifting of the nut-fork 42, which makes the belt slide along the drums 12 13 toward the larger end of 13 by a difierent amount for each layer as determined by different radii of the canh 59, (calculated for this,) which limits the fall of the lever 49, and consequently the shift of the belt on the drums 12 13.

In order to maintain the regularity of the layer, the traverse of, the bobbin must vary according to the thickness of the threacl,or the thread would not be uniformly distributed on the available length of the bobbin. Moreover, the pitch of the winding must remain uniform for all layers and must be approximately equal to the thickness of the threads. The first condition is attained by the possibility of shifting the pin 33, which moves the lever 35,and thus modifying the stroke of the lever and the longitud inal stroke of the bobbin. The fork 40 may also be shifted along the rod 37 to allow of symmetrical distribution over the twohalves of the bobbin. The secondconditionn amely, regularity of the pitch of the windingisattained by the differential gear and the parts worked by it. The shaft 25 making one revolution every timet he bobbin makes one turn more than the flierthat is to say, for every convolution on the bobbinthe threaded sleeve 32 moves whatever be the size of the bobbin and for every convolution on the bobbin to a constant extent, depending on the pitch of the screw 29 and on the ratio of the gears 26 and 27. The movement of the sleeve for each convolution may, therefore according to the gearing employed, be as small as desired and so proportioned as to give the bobbin for every convolution a traverse equal to the thickness of the thread, which movement will remain the same however the bobbin increases. The Winding is therefore regular, capable of regulation, and mathematically constant. The layer of winding being uniformly distributed in convolutions with a pitch equal to the diameter of the thread will have uniform diameter over all the layer. On the other hand, as the belt of pulleys 12 and 13 allows of retarding the bobbin in such manner that the quantity wound on is the same for each layer per turn of the flier the twist of the spinning will be uniform. It can therefore be regulated as desired and remains constant for a given time in number and length of twists. In respect of tension it can be as desired, since it has no influence on the operating parts. Threads of either right or left pitch can be produced, according to the direction in which the driving-belt and the belts of the differential gear move.
